8.22 Data Operation Instruction
Adding 32-bit data
DWSUM(P)(_U)

Processing details
• These instructions add the (n) point(s) of 32-bit binary data in the device starting from the one specified by (s), and store the
result in the device specified by (d).
Precautions
In the 32-bit operation, the acquired sum is 64-bit data. The FX5 CPU module cannot handle 64-bit data. When the sum is
within the numeric range of 32-bit data (K-2147483648 to K2147483647), however, the FX5 CPU module can handle the low-
order 32 bits of 32-bit data as the sum while ignoring the high-order 32 bits.
